Inasmuch as this invention relates particularly to the printing nechanism parts of the ,machine not relating thereto and believed tobeunnecessary to a complete 1111- derstanding of the invention have beenomitted-from the drawings.

,In the specific form herein shown, the improved printing mechanismcomprises an intermittently rotatable platen supported on an oscillatingcarriage whichis actuated by improved mechanism to move the platen intoandout ofengagement with the stencil. An improved inkktransferringmechanism comprising a plurality of rollers isarranged to transfer inkfrom a fountain to the platen which wipes'the ink from .oneiof thedistributing rollers. Certain. of the rollers are made of metal] andothers 7 are provided with composition Shells. In orderjto prevent thecomposition rollersfrom becoming flattened thliqughcontact with otherrollers during a 1mm period when not in motion, improved m anisrri is '1pro ided. for m e he c m ppsiem mners to contact Wit h b rollers. Thislastmentioned mechanism is controlled by the same means which controlsthe starting] and stopping of themachingso hat, the. tell r arfeutoma icy t ew ou f beect nsrelntioi With one anet HPW the SW pine ef henm n 1 hprintingmecl 'ln is applied .to an addressing l lathine 'omprising aframed, avingahorii iontahtable or bed 2, on vvliic .is mounted apair ofspaced rails3 forming a guideway for supporting and gu idi n g a. pinralityof stencils 4, ,v fh'ich ,are fec bserial'iin tlnfough the liiichine by an endless conveyer 5,so as tobe operated'npon the improvedprintingmechanism and by various Qi'l'lk'fi.

Extending transmechanisms, not shown.

verselythrough the bed 2, is a passage .(3 located below the stencilguidewayfforreceiving a stack of. envelopes, not shown, upon whichtheaddresses are ,printed from the stencils.

Locateddirectly below the stencil guide- Way, in vertical ,alinementWith-theplaten, is a vertically movable anvil 7,, hioh is adaptedtoraise the envelopesinto position to be acted upon by thestencils.

In the form shown, the improved printing device comprises animpressionmechanism and a ink.tr ns e'rie mecha i m .1

bodim'ent shown, the imprpved The improved impression mechanism Acomprises an impression element or platen 8, rotatably mounted on anoscillating carriage 9, which is actuated so as to move the platentoward and away from the stencils 4.

In the construction illustrated, the platen 8 comprises a suitable pad10, mounted on a metal base 11, having arms 12, which are fixed on arotatable shaft 13 journaled in the frame 9. The face of the pad is of asize and shape which will conveniently fit within the stencil in makingthe impression.

Fixed on one end of the shaft 13, is a mutilated gear 14 meshingwithanother mutilated gear 15 which is fixed on a stud l6 journaled in theoscillating frame 9 and driven through a train of gears 17, 18, 19 and20. The gear 17 is fixed on the stud 16 and the gear 18 is loose onashaft 21 'journaled in a pair of spaced upstanding brackets 22 and 23 onthe frame 1. The gear 19 is keyed to a shaft 24 journaled in the bracket22 and the gear is fixed on a drive shaft 25 which is journaled in thebrackets 22 and During the operation of the printing mechanism, thedrive shaft 25 is rotated continuously by an electric motor or othersuitable power means, not shown, which may be controlled by a foot pedalconvenient to the operator of the machine.

Through the operation of the drive shaft 25, the gears 20, 19, 18, 17-and15 are rotated continuously. During the impression operation, whenthe platen pad 10 is in contact with the stencil, the platen shouldmomentarily cease rotating. For this reason, the gears 14 and 15 aremutilated so as to provide smooth portions 26 and 27 respectively whichslidably engage each other during the printing operation. Projectingradially outwardly from one side of the gear 14, is a cam 28, located soas to engage a pin 29 on the rotating gear 15 to insure proper meshingof the gears 14 and 15 after the printing operation.

In the specific form shown, the carriage 9, which carries the platen,comprises a pair of end members 30 connected together by integral crossbraces 31 and 32. Formed on the end members 30. are bosses 33, which arejournaled on bushings 33.1 on the shaft 21 which forms the pivot onwhich the carriage 9 oscillates. The carriage 9 is oscillated by amechanism which includes a pair of links 34 and 35 and a bell crank 36.The link 34 is rigidly secured to the brace 31 of the carriage, and thelink 35 is pivotally connected to the inner ends of the link 34 and bellcrank The bell crank 36 is pivoted on a pintle 37 supported in thebrackets 22 and 23 at the rear of the frame. The lower end of the bellcrank 36 has a roller 38 which rides on a cam 39 fixed on the driveshaft 25, whereby the rotation of the shaft 25 imparts an oscillatingmovement to the carriage 9. The roller 38 is normally urged intoengagement with the cam 39 by a spring 40 bearing between the lower endof the bell crank 36 and a bar 41 extending between the brackets 22 and23.

The improved ink transferring mechanism B, as herein shown, comprises aplurality of coacting rollers 42, 43, 44, and 46, arran ed to transferink from a fountain .47 to the platen pad 10. The rollers 42 and 44 arepreferably made of a suitable resilient composition and the rollers 43,45 and- 46 are referably metal.

T 1e roller 42 is rotatable'on a shaft 48 carried at its ends by a pairof arms 49, pivotally connected to the carriage members 30 by pins 50.In order to permit the roller 42 to yield when in contact with theplaten 8, it is resiliently urged toward the platen by a pair of springs51 bearing against the ends of the shaft 48 and seated in slots 52formed in the arms 49. The roller 42 is normally urged into enga ementwith the roller 43 by springs 53 exten ing between the arms 49 and thebosses 33.

The roller 43 is fixed on the drive shaft Secured to oneend of theroller 43, is a gear 54 adapted to mesh with gears 55 and 56 mounted atone end of the rollers 42 and 44 respectively, for rotating the rollers42 and 44.

The roller 44 is provided with a pintle57 f The levers 59 and 60 arepivoted on a shaft 63 supported in the brackets 22 and Extending betweenthe levers 59 and 60, and rigidly connected thereto, is a brace 64.Mounted on the outer end of the lever 59, is a roller 65 which engages acam 66 fixed on the drive shaft 25, whereby the rotation of the shaft 25oscillates the levers 59 and 60, thereby periodically moving the roller44 out of engagement with the roller 45. The roller 44 is normally ur edinto engagement with the rollers 43 am 45 by meansof a spring 67extending between the arm 60 and the shaft of the roller 45.

During the operation of .the printing mechanism, the roller 44 rides upand down on the roller 43 so as to move toward and away from the roller45, to periodically wipe ink from the roller 45 and transfer it to theroller 43. When the machine is stopped, the rollers 42 and 44 are bothdisengaged from the other rollers. The means for disengaging the rollers42 and 44 from the other rollers comprises an arm 68 pivoted on a stud69 mounted in the bracket 23. Mounted on step-by-step movement along theguideway.

. of" the arm 68. a a p The roller 45 has a pintle 74, supportedin thearm 68, is a cam 70, which engages a pin 71 on the Tadg'aceiit"; 58 "forraising the roller 44 and ts supporting linksatfdievers,

The rollrs 44and 45rotate in the same direction,.aiid, therefore, when the two are incontaet,"theroller 44 wipes ink from the surface of the roller 45. Inorder to permit variation of the throw of the pawl 76, a pin and slotconnection 82 is provided between thelink 77 and bell crank 78. The pawl76 is normally retracted by a spring 83 which extends between the link77 and a peg 84 mounted on the base bed 2. The spring 83 also serves toretain theroller in contact with the cam 81.

The inking roller 46 is supported in a pair of hangers 85 pivoted at oneend on a pin 86 extending across the fountain 47. The roller 46 isyieldingly urged into contact with the roller 45 by springs 87 hearingbetween the outer ends of the hangers 85 and the bottom of the fountain47.

Mounted on the frame 1 at the rear of the printing mechanism, is anelectric switch 88 having an operating arm 89 connected to the arm 68 bya link 90. The switch 88 is in the electric circuit which controls theoperation of the printing mechanism and is opened and closed by themovement of the arm 68, which simultaneously moves the rollers 42 and44. a i

In operation, the stencils 4 are fed in a 3 so as to position onestencil at a time directly below the platen 8.

During the operation, of the printing mechanism, the shafts 21 and 25rotate continuously for driving respectively the ink distributingrollers and the cams 39, 66 and 81. Through the operation of the cam 39,the carriage 9 is oscillated so as to move the platen pad 10 into andout of engagement with the stencils. Through the action of the gears 14,15, 17, 18, 19 and 20, the platen 8 -"Alt houghbutone spe' ill 11$invention has beendierein shown and described, it' will be 'undt-irstoodthat minder.
